GTi ordered 29th August.
Read a post on here some time ago that delays in production were caused by VW not receiving adequate supplies of the RCD510.
My dealer has confirmed that this is one of the major problems. My trade-in was valued in August but they allowed for 3 months further depreciation as, at that time, they expected me to get my new GTi in Nov/Dec.
Build week still not confirmed and is now provisional week 6. Dealer wants my trade-in in January and will give me a [new I think] loan car; also offered me £200 off new one as a good will gesture for being so patient. No VAT increase will be passed on to me.
Although impatient, I'm now resigned to waiting until March for my car; at least it will be on a 10 plate.
